DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a view from the upper surface of a typical embodiment of a body board 100 and FIG. 2 is illustrated a view from the underside of the body board 100. The upper surface of the board is configured to define a shallow concave depression 109 sized to accommodate the width of the body of a user disposed across the majority of the width of the board and extending from the forward midsection of the board through the trailing end of the board such that the channel is open at the tail end of the board. The underside of the board is provided with two essentially parallel channels 103 and 104 disposed in mirror image fashion on each side of the center longitudinal axis of the board. The channels 103 and 104 is have closed proximal ends 107 and 108 respectively. The channels 103 and 104 are disposed near the midsection of the board wherein the channels extend completely through the rear end of the board such that the distal ends 105 and 106 of the channels are open. The body board 100 further comprises a hole or opening 110 extending through the thickness of the board, which is positioned near the frontal section (nose) 101 of the board and is configured to be suitable for the attachment of a tow rope or leash 115, and other openings or holes 111, 112, 113 and 114 extending through the thickness of the board and disposed along and parallel to the outer edges of the frontal section or nose 101 of the board wherein the openings are suitable for the attachment of a grip handles 116 and 117.

In FIG. 3 and FIG. 4 are illustrated an orthogonal top view and an orthogonal bottom view respectively of the body board 100 illustrated in FIG. 1 wherein the substantially semi-circular or semi-elliptical shape defined by the edges of the body board nose 101 is clearly depicted. Also depicted in FIG. 3 are the features defined as the maximum board width labeled W1, the minimum board width labeled as W2 and the board length labeled L. In FIG. 3 is further illustrated the parallel channels 103 and 104 in the bottom surface of the board. In typical embodiments of the invention the maximum board width W1 is from about 1.1 to 2.0 times the minimum board width W2, in certain other embodiments the maximum board width W1 width is from about 1.2 to 1.8 times the minimum board width W2, while in other certain preferred embodiments the maximum board width W1 is from about 1.3 to 1.6 times the minimum board width W2. Also, in typical embodiments of the invention the board length L is from about 1.1 to 3.0 times the maximum board width W1, and in certain embodiments the board length L is from about 1.2 to 2.5 times the maximum board width W1, while in certain preferred embodiments the board length L is from about 1.5 to 2.0 times the maximum board width W1.

In FIG. 5 is illustrated an orthogonal side view of the embodiment of the body board illustrated in FIG. 1 that clearly shows the variation in the depth of the channel 104 from the closed proximal channel end 107 to the open distal channel end 105. An important functional feature of the body boards of the present invention is the variation in depth of the channels in the bottom surface of the boards wherein the minimum channel depth is at the closed proximal end of the channel and the maximum channel depth is at the open distal end of the channel. In typical embodiments the maximum depth of the channels at the tail end of the board is from about 5% of the maximum board thickness to greater than 50% of the maximum board thickness. In certain embodiments the maximum depth of the channels at the tail end of the board is from about 10% of the maximum board thickness to about 50% of the maximum board thickness, while in certain preferred embodiments the maximum depth of the channels at the tail end of the board is from about 15% of the maximum board thickness to about 40% of the maximum board thickness. Also in the embodiment depicted in FIG. 5 the underside 120 of the board 100 at the frontal 101 is gently sloped or tapered toward the top surface of the board. In all such embodiments, wherein the frontal section or nose of the board is so configured, the overall dimensions are rendered such that the proximal ends of channels in the bottom surfaces are closed and do not extend into the sloped or tapered area of the frontal section.

The cross sectional orthogonal views illustrated by FIGS. 6, 7 and 8 clearly show the variation in depth of the channels 103 and 104 in the body board 100. FIG. 6 is a sectional orthogonal view taken through an area near the center of the board while FIG. 7 is a sectional orthogonal view taken through an area between the center and the tail end of the board and FIG. 8 is a sectional orthogonal view taken through an area near the tail end of the board. In FIG. 9 is depicted a sectional orthogonal view of the body board 100 illustrated in FIG. 3 wherein the section is taken parallel to the longitudinal axis of the board and cuts through the channel 104 showing the variation in depth. This FIG. 9 also clearly illustrates the concave depression 109.

In FIG. 10 is illustrated a top perspective view of an embodiment of a body board 200 wherein the upper surface of the board is configured to define a shallow concave depression 205 sized to accommodate the width of the body of a user disposed across the majority of the width of the board and extending from the forward midsection of the board through the trailing end of the board such that the channel is open at the tail end of the board. This embodiment of body board 200 also comprises skegs or fins 210 attached to the bottom surface at the tail end. In FIG. 11 is illustrated a bottom perspective view of the body board 200 as illustrated in FIG. 10 wherein is clearly shown that the attachment points the fins 210 to the bottom surface of the board 200 are between the channels 206 and 207 and the edges of the tail end of the board. Also, in this and other such embodiments the skegs or fins 210 as well as the longitudinal axes of the channels 207 and 208 are disposed to be parallel to the longitudinal axis of the board 200.

FIG. 12 is a bottom orthogonal view of a body board 400 configured to define two channels 410 and 411 in the bottom surface. In this embodiments and other similar embodiments the closed channel proximal ends 412 and 413 are disposed in the frontal section of the board forward of the points 415 that define the maximum width of the board 400 and the channels extend through the tail of the board and are open at channel distal ends 416 and 417.

FIG. 13 is a bottom orthogonal view of a body board 500 having a single channel 510 in the bottom surface wherein the closed channel proximal end 511 is disposed at in the frontal section of the board near points 515 that define the maximum width of the board 500 and the channel extends through the tail of the board and is open at channel distal end 512.

Additionally, the body boards of the present invention can be conveniently fabricated in different sizes to accommodate different sized users without compromising function. Therefore, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the invention, including variations in size, materials, shape, form, function and manner of operation, assembly and use, and all equivalent relationships to those illustrated in the drawings and described in the specification, that would be deemed readily apparent and obvious to one skilled in the art, are intended to be encompassed by the present invention.
